显示启动画面后的离子android白屏

问题描述

我已经使用 ionic cordova build android 构建了一个 apk 文件.我已经使用 Genymotion 模拟器打开了该应用程序.当我打开应用程序时，它会启动并显示启动画面.之后永远出现一个白屏(我可以关闭应用程序.但是当我再次启动时，同样的事情会发生).

I have built an apk file using ionic cordova build android. And I have opened that app using Genymotion emulator. When I opened the app, it starts and displays the splash screen. After that a white screen appears forever (I can close the app. But when I start that again, same thing happens).

我在 android studio 控制台中捕获了错误.

I have captured the error in the android studio console.

他们来了，

然后我在那个 apk 中打开了 main.js 文件.在第 40 行，我找到了这段代码.

And then I have opened the main.js file in that apk. In line 40, I have found this code.

然后我浏览了 pages (./pages/scanner/scanner.ts) 文件夹中的scanner.ts.我没有发现任何问题.当我使用 cordova run browser 运行它时它可以工作.

Then I browsed the scanner.ts in pages (./pages/scanner/scanner.ts) folder. I did not find anything wrong. It works when I run that using cordova run browser.

scanner.ts

推荐答案

将tsconfig.json中的target值由es6改为es5 有效.
例如.target":es6" >>> target":es5"

Changing the target value in the tsconfig.json from es6 to es5 has worked.
Eg. "target": "es6" >>> "target": "es5"

注意:除非您明确声明，否则此问题不会自动发生在项目中.

Note: This problem will not automatically happen to the project unless you declare that explicitly.
